Lord Nachzehrer is the ruler of the Abhorred hordes. Once an honored member of the Sanguine Court, his obsession with blood infusions and genetic modifications had irreversible effects on his personality and physiology.
He is driven incessantly to become himself the perfect form of an apex predator, to emulate the perfect hunter of the night, as are the Cryptstalkers and Bloodhounds. On his insane quest, Lord Nachzehrer began to gain power by mixing his blood and that of his servants with any fiendish things that stalk the dark corners of the world.
With every new infusion, his body and mind changed, becoming more erratic and unstable, until he was exiled to live among his forlorn castle, far from the courts of his former kin. There, he delves deeply into lost sciences in his laboratory, where his experiments continue unhindered.
Though a wayward lord, Nachzehrer still holds a tenuous relationship with the Sanguine and other vampire bloodlines, who value and use his creations for their own purposes but shun him for his deviancy otherwise, afraid of what he has become. In his exile, Lord Nachzehrer has grown incredibly powerful, drawing from a strange, enormous beating heart which he keeps chained within his fortress keep, found in some devilish place only he may know.
